Unable to receive SSL VPN tunnel IP address (-30)

I have multiple users that are getting this error message intermittently. The users are connecting from India and my office is located in the U.S. There are plenty of IP addresses available in the pool. Could this be a internet bandwidth issue? Any suggestions would be greatly appreciated.
 
Thank you,

    I high   unlikely, how big is the pool? Are all users using the same pool or do you have multiple   portal with unique defined pools for tunnel-mode
     
     
    i.e
     
    web portal USusers
          pool ABC
     
    web portal  INusers
          pool   DEF
    etc....

    Than your problem is not the pool size. Your problem is something else.

    just a wild guess: latency? maybe the time between request and reaction of the FGT is too long (though I have no information on this internal detail).
    OTOH, have you checked the MTU? this can bring up a lot of funny effects like some traffic making it through and some not.

    did you managed to understand why do you have this issue?
    I start experience the same issue. It happens randomly. I'm sure that is not related to the IP Pool usage. I have a pool of 200 IPs and when the issue happen only 94 users were logged in.
     
    Thanks

    I am having the same problem. Has anyone found a solution yet?
    Issue is the same, tested from different locations and ISP's
    Can it be a firmware issue? I have v5.6.2 build1486 on a 30E
    Firewall is connected to ISP's firewall, is it the same in your case?

    When I faced the issue the firewall was in 5.2.4, last week I upgrade the firewall to 5.4.5. For now the issue seems to be gone.

    There's a firmware upgrade available for my firewall. I will try that too.

    I upgraded the firmware, problem seems to be solved.
    Don't know what solved the problem exactly.
    The firmware upgrade? Or the reboot of the firewall?
